give it time it takes 6 weeks to stabilise and can take longer with a more mature system.
The fading or lightening of corals is the positive change, once I see PO4 at zero then we can look at adding reef booster. If your system is really mature with a nutrient sink you may need to give the system a help in hand with ultra power phos, this goes with any ULNS. These systems can only reduce low levels of PO4 and all advise using phos remover to get levles down first, but as we are assessing the power of Prodibio the review is best run without any external intervention where at all possible.
